Your car is a nice example of one that hasn`t been altered a lot. One way you could go is to try to find a stock intake with a Carter AVS. I`d imagine your car should boil the tires without a problem once you get it tuned correctly. I`m running 93 octane gasoline and right about 34* total timing with my entirely stock 68 340. I am using an electronic ignition instead of the dual point.
